David Walliams as a ‘frog fish’ & Kimberley Walsh in new Sport Relief 2014 promo!

The Britain’s Got Talent star has always been a strong supporter of the Sport Relief annual campaign and while he might not be swimming the Thames again – not after all the health problems that came hand in hand with the last one – the new dad as showed up in a brand new promo video for the 2014 special.

The video was released this morning and also features Olympic cyclist and former Strictly Come Dancing contestant Victoria Pendleton and retired British middle distance athlete Kelly Holmes.

Davina mcCall will be playing a big role in this year’s fund-raising activities, as she’s agreed to take on the biggest physical challenge of her life later this month.

Aptly named the BT Sport Relief Challenge: Davina – Beyond Breaking Point, the challenge will see the much-loved presenter attempting to cycle, swim and run over 500 punishing miles from Edinburgh to London in just seven days.

Sport Relief 2014 will take place between Friday 21 to Sunday 23 March 2014.

There will be the annual event, The Sport Relief Mile, as well as three major cycling events (in London, Manchester and Glasgow) and over 600 Swimathons, under the umbrella title of “The Sport Relief Games”.

Sports stars Jessica Ennis-Hill, Ellie Simmonds and Chris Hoy will all front the games this year.
